What are the differences? Which one is the best?
For P20 to P10 DIP display we recommend MBI5041 or MBI5043.
For P2.5 to P1.6 SMD display we recommend MBI5252 (16 scan) or MBI5153 (32 scan).
JXI5020 / MBI5020 is a low end China made chip for the Chinese market and should be avoided at all costs.

* With Scrambled-PWM (S-PWM) technology, Pulse Width Modulation is enhanced by scrambling the “on” time into several “on” periods. The enhancement equivalently increases the visual refresh rate. When building a 16-bit color depth video, S-PWM reduces the flickers and improves the fidelity.

There are two key features of MBI5152. First, it is to provide excellent output current that is as low as 0.5mA and its accuracy is less than ±3% among chips. In the past, since the luminous efficacy of LED was lower; therefore, it was necessary to increase LED current to make a LED display brighter. However, nowadays because the demand of indoor usage is booming, the efficiency of LED has been improved, and the trend of pitch requirement is getting finer and finer. Therefore, the key point should be low current accuracy of driver ICs. Second, MBI5152 can optimize color uniformity of super fine pitch display. As using MBI5152 and NOVASTAR solution for a fine pitch display, annoying problems, such as: dim line, lower ghost effecting, non-uniformity at low gray scale and color shift at white balance can be solved.
MBI5153 solves 6 display challenges of fine pitch LED displays :
1. Gradient dim line
2. Cross pattern from a failure LED
3. Dim line at first scan line
4. Lower ghosting
5. Non-uniformity at low grayscales
6. Color shift at low grayscales
